I would love to go visit the Wolfskill experimental fruit orchards in Winters, CA, but I have two questions:
1) When would be a good time to visit?
2) How do you arrange a visit? I looked on the Wolfskill website and the only contact information I could find was for Katherine Pope. I emailed her, but received no response.

http://www.ars.usda.gov/pandp/people/people.htm?personid=44926 Is the fellow that is in charge of the USDA program at Davis.

Be advised that they often cannot accept visitation requests because is limited personnel, and may not respond for the same reason.

Message has been sent. Crossing my fingers and hoping that I get a reply.

How did this work out? I would like to visit sometime and was wondering how hard it is

Maybe smatthew got in and wouldn't leave. I might be tempted to do that if I got into a restricted figgy wonderland.

I think they would be happy to show you, at least I hope.

I have gotten in multiple times and left every time! And despite the strong urge, my clippers never left the truck. They are happy to show off their collection. Email them and be patient.
